Summing up the results of our tests, we can say that the Radeon HD 4670 passed them successfully due to the impressive computing capabilities and strong texture-mapping section of the RV730 chip. However, the new card’s performance could not be but affected by the reduced number of raster-back ends and the cut-down 128-bit memory bus. You can look at our summary diagrams to evaluate the card’s success.
The Radeon HD 4670 isn’t brilliant at 1280x1024, being faster than the GeForce 9600 GT in four tests only. And it is only in Half-Life 2 that its advantage is over 10%. In the other tests the new card is slower than its opponent by 6% to 42%. But you should keep it in mind that the GeForce 9600 GT has a 256-bit memory bus and costs more. The Radeon HD 4670 looks good in comparison with the GeForce 9500 GT 256MB, losing to it somewhat in one test only (Tomb Raider: Legend).
Despite having only eight raster back-ends, the Radeon HD 4670 looks better at 1600x1200 when it beats the GeForce 9600 GT in six tests. Its efficient graphics memory management helps to achieve those victories. Considering the equal results in Command & Conquer 3, the overall score is 6:9 in favor of Nvidia, but the GeForce 9600 GT is more expensive. When competing in the same price category, the Radeon HD 4670 is unrivalled, leaving no chance to the GeForce 9500 GT 256MB. The latter could hardly be competitive even if it had 512 megabytes of onboard memory.
Oddly enough, the new entry-level card from ATI got most victories at a resolution of 1920x1200 it is not actually meant for. It beats the GeForce 9600 GT with a score of 9 to 7 but cannot provide a playable frame rate in most of the games. We are talking about a $79 product after all. The GeForce 9500 GT 256MB looks hopeless against the Radeon HD 4670.
So, the Radeon HD 4670 performed well in our tests considering its low recommended price. It is somewhat inferior to the GeForce 9600 GT in most of today’s games, but costs less (and may get even cheaper in the future) and has more advanced multimedia capabilities. Thus, ATI’s new card is surely the best entry-level product now.
The particular model we discussed today, the PowerColor PCS HD4670 512MB GDDR3, features a unique PCB design and a silent but effective cooler. If you are limited in your PC budget, this graphics card is going to be a good choice. For a modest sum of money you will have good performance at resolutions up to 1680x1050/1600x1200 and a full spectrum of multimedia functionality including support for HD audio.
